DOOR-STOP.

SPECIFICATION forming part of Letters Patent No. 760,528, dated May 24,1904.

Application filed September 15, 1903- Serial No. 173,240- (No model.) I

To all whom it may concern:

Be it known that I, CHARLES C. DAVIES, a citizen of the United States,residing in N ewport, in the county of Campbell and State of Kentucky,have invented certain new and useful Improvements in the Construction ofDoor- Stops; and I do declare the following to be a clear, full, andexact descri pti on thereof, attention being called to the accompanyingdraw,- ings, with the reference characters marked thereon, which formalso a part of this specification. V

This invention relates to improvements in the construction ofdoor-stops, which are devices provided for thepurpose of holding a doorin a certain position. This position may be one in which the door iscompletely closed, occupying a position between the jambs of itsopening, and in which case the device, in conjunction with a socket-holeor keeper, serves to lock the door. Another position may be one at anypoint to'which it may be swung when open, in which case the deviceserves to merely hold the door against such causes which tend to closethe same unintentionally'as,for instance, drafts, unequal hanging, &c.In such case the device operates by spring-pressure,

a bolt being caused to impinge against the floor, it being held incontact therewith by the spring-pressure. Some of these devices servefor either purpose only, while others maybe used in this .doublecapacity. My device belongs to this latter class and may be used toeither positively lock the door in its closed position or hold it byyielding spring-pressure in an open position.

The objects of my invention are to construct such a device in the mostinexpensive manner possible without sacrificing durability andusefulness. These objects are attained by the selection of the material,by the manner of working the same, and by the particular arrangement ofthe parts which facilitates their quick and convenient assembling.

In the following specification, and particularly pointed out in theclaims following, is found a full description of the invention, togetherwith its manner of construction, which latter is also illustrated in theaccompanying drawings, in which- Figure 1 shows one of my devicesattached to the lower outer corner of adoor and in a position where, inconjunction with a socket or keeper, it looks such door in a positivemanner. Fig. 2 shows the device inactive. Fig. 3 shows the device in asectional side view, it being then used to'hold the door in an openposition by springpressed contact of the device with the floor. Fig. 4is a horizontal section of the device. Fig. 5 shows the blank out ofwhich the front part of the bolt-housing is formed. Fig. 6 shows theback wall of the housing. Fig. 7 shows the front part of thebolt-housing in perspective view and r as the same is shaped out of theblank shown in Fig. 5.

The operatively-active part of the device is a bolt 10, provided on itslower end with a rubber tip or shoe 11 to increase the frictionalcontact with the floor when used in a manner as shown in Fig. '3 and toprevent scratching of such floor in case an attempt is made to move thedoor before raising the bolt. To provide these shoes, I use rubbertubing, which I cut in pieces of proper length and which are held inplace by being shoved onto the reduced end 12 of the bolt and against ashoulder1-3, resulting from suchreduction. The outer diameter of thisshoe is such as to prevent it from projecting beyond the diameter of thebolt, so that in case the device is used. in combination with a keeper14:, as shown in Fig. 1, any lateral strain or bearing is not againstthe rubber, but'taken up by the metallic part of the bolt.- This latteris fitted into a housing 15,. the lower end of which is open, and it hasa. tendency tomove out of this opening, imparted-"by a spring 16 actingagainst its" upperend This spring isalso confined in the same housingand held in place by the'closed .upper end 17 of such housing.

-Thebolt is provided for its manipulation with a'knob 18, carried at theouter end of shank 19, which projects through a slot 21 in the frontpart of the housing. This slot -is of such a length vertically, that thebolt from its highest inoperative position, as shown in Fig. 2, may movedown sufficiently into a locking position within keeper 14;, as shown inFig. 1, in which the door is positively locked. This 2 leaves the boltof course free to occupy any intermediate position for purposes ofhaving contact with the floor and, as shown in Fig. 3, allowing alsosufiicient play to accommodate any irregularities in the surface of suchfloor. To hold the bolt in an inactive position against the positiveaction of the spring, it is necessary to lock it positively in itshighest posi tion, as shown in Fig. 2. This is done by turning shank 19of knob 18 into either one of two notches 22. By providing two of these,

notchesno mistake can be made in turning the bolt, nor is it required toascertain first to which side the bolt should be turned. The boltmay bedead-locked by a similar manipulation when in its loIwestor positivelocking position, as shown in Fig. 1, where again notches 23 areprovided, they being also duplicated for the same reasons stated'above.

The housing is held in place on thedoor' by attaching-lugs, one, 2 1,at'thelupper end and two lateral ones, 25 25, near its'lower end. The:

housing is made out of sheet metal and formed to the shape shown in Fig,7 out of the blank shown in'Fig 5. This blankis cut out in one piece,containing all the attaching-lugs and also the upper end necessary toclose the llOLlSf ing to confine spring 16. Slot '21 witlrthe notches atboth its ends is simultaneously produced. After the housing is formed toshape, as shown in Fig. 7 out of the blank, as shown in Fig. 5', bolt 10and spring 16 may be readily dropped into position througlr'the at thetimeopen rear part'of the housing. (See Fig. 7.) After this this openpart is" closed by the rearwall 26, fitted so as to rest againstthe'edges of the housing. It is held in place by clenching-lugs, two ofwhich, 27 27, are

' provided at theupper. end, which are bent over and turned down againstthe upper attaching-lug 24;, while below similar lugs 28 28 are used,two on each side, which in like manner engage the lowerattaching-lugs'25.

In order to provide the necessary metal for these clenching-lugs thisrear wall is made correspondingly longer and wider.

"It will be noted that this device satisfies all requirements, servingas a locking device to andno difficulty .lis encountered in having shank19 to assume its proper position within slot 21. The bolt with its knob18 and shank 19 may therefore be all cast in one piece.

The rubber shoe is provided in the cheapest possible manner, itsmaterial in proper shape being purchasable in the markets, and itsattachment is equally simple.

The arrangement of the lugs might be reversed-that is to say, theattaching-lugs might be formed on the back part 26 and theclenching-lugs on the front part 15.

' The locking engagement of the shank within the lateral notches in slot21 maybe intensified by undercutting these'notches, as shown Havingdescribed my invention, I claim s new- In a door-stop for the purposedescribed, the combination of a bolt-housing of sheet metal closed atits upperend and consisting of two' parts, a front part substantiallysemicircular and a flat back part, attaching-lugs on one of'these partsand clenching-lugs on the'other one, the two parts being held to eachother by the clenching lugs engaging the attaching-lugs, all of saidlugs, as well as the end of the housing being formed integrally with theparts mentioned, abolt fitted between tlieseconne'cted parts, anactuating-spring behind it and a knob to manipulate the bolt.

2. The blanks for a two-part, sheet-metal bolt-housing which latter'isto be closed at one end', there being a blank for the front part whichcontains integrally the part forming the end of the housing and a blankfor the rear part of the housing, one of these blanks containingintegrally the attaching-lugs for the housing while the other containsintegrally clenching-lugs which serve finally to connect the two partsof the housing by engaging the attaching-lugs of the other part.

In testimony whereof I hereunto set my sig nature in the presence of twowitnesses.
